Chrissy Teigen to Solicit Baby Names on Twitter

The 32-year-old model and television personality said in an interview with E! News published Thursday that she plans to keep details about her unborn second child private for as long as she can.

"We knew when we put [the embryo] in but John was like, 'Make sure you don't say it. Let's have one thing for us,'" Teigen, who conceived via in vitro fertilization, said.

"Of course I'm probably going to end up saying it but I'm just going to do this favor to him for as long as I can," she added.

Teigen and Legend already share 21-month-old daughter Luna Simone, who was also conceived via IVF. The model said she and Legend have yet to choose a name for baby No. 2, although Teigen gets to pick this time around.

"Names are tough," the star said. "What I learned was never share your ideas. If you have a name idea, somebody is going to be like, 'No, I knew a person by that name in high school and they were gross.' That always happens."

"John picked Luna so I decided I get to pick this one. I don't know what to do. Take it to Twitter," she joked.
